Cisco DNA Traffic Telemetry Appliance

March 22, 2021 ,

Cisco released DNA Traffic Telemetry Appliance which will act as a sensor platform and provides endpoint and application analytics solutions on Cisco DNA Center. 

As you may knew that SPAN (Switched Port Analyzer) is used to get the network traffic mirrored from switches and routers and now that will be fed into the Cisco DNA Traffic Telemetry Appliance mirroring interfaces from where you will get the visibility of the devices connected to the switches and router. 

We are using NBAR on Cisco Catalyst switches and that data will be used to analysis to provide the meaningful information.

Similarly in the Cisco SDWAN environment, we are using SD-AVC and can be fed to the Cisco DNA Traffic Telemetry Appliance to get more useful information.
